Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding precision, stability, and smooth tuning performance with its refined 1:18 gear ratio. All components are CNC-machined to exact tolerances, surface-finished, and equipped with a self-locking drive for consistent and reliable operation. Each closed housing is permanently lubricated with Schaller special grease to provide completely maintenance-free functionality.
Constructed with high-grade brass string posts precisely fitted into the housing, the M6 Pin ensures optimal tuning stability and long-term wear resistance. The innovative stepped M6 flanged washer reliably centers the string post through the banjonut, eliminating tilting movement and taking pressure off both the post and mounting points without requiring a stepped headstock bore.
Featuring a 0.4 in (10 mm) pin spacing and a 0.3 in (8 mm) distance between pins and post center, this model provides seamless mounting on compatible instruments. Its robust closed design and precision-engineered mechanics make it an exceptional upgrade for demanding musicians seeking uncompromising tuning accuracy.
